Elements of Microstructure
(Prof. Dr.-Ing. Gunther Eggeler)
This lecture is given in English and was devised for the master students of the master course Materials Science and Simulation. It is also well suited for students who take up materials studies at a later phase. It provides a focused introduction to the basics of our field. It is also well suited for materials students who wish to familiarize themselves with the English technical terms of our field. The lecture starts with an explanation of the atomic structures of amorphous and crystalline states. The concepts of nano, micro and macro structures of engineering materials are introduced. Key diffraction methods and microscopic methods are treated. There is a strong focus on crystal defects (vacancies, foreign atoms, dislocations, interfaces), which represent the elements of a material’s microstructure. The lecture treats thermodynamic aspects of point defects, stresses and elastic strain energies associated with dislocations, internal and external interfaces and three-dimensional defects such as pores, precipitates, dispersoid particles, fibers and inclusions. Important thermodynamic (phase stabilities and phase diagrams) and kinetic aspects (diffusion, phase transformations, TTT diagrams) are introduced. The key role of the microstructure of an engineering material in governing many of its important service properties is highlighted. The lecture is held in the winter semester on Wednesdays from 2:00 to 4:00 p.m.
